General Plan

For my project I am comparing the amount of toxin in natural snow to man made snow.I am going to collect snow from a ski mountain and an untouched mountain and melt down the snow.Then I am going to take a paper filter and a funnel. I am going to dump the water into the filter with the funnel and after all the water went through I will then take the paper from the two melted snow samples and weigh the differences for the most bacteria I then take two more samples and have them measured in a lab. After this I will check my hypothesis and get my answer.

Potential Problems And Solutions

1.Dirt might drift into the snow
2.The filter and funnel might be dirty
3.If i touch the snow with my hannds it could contaminate it

Safety Or Environmental Concerns

Experimental Design

(add the correct headings from the experimental design page before beginning)

Number Of Comparison Categories:

2, natural and man-made snow

Number of Comparison Samples:

10, 5 natural and 5 man-made

Number Of Observation In Each Sample:

5 observations

When data will be collected

march,11, 2013

Where will data be collected?:

the data will be collected in my science class room, and at my house in my kitchen

Resources and Budget Table

Item	Number needed	Where I will get this	Cost
paper filter	10	school	?
funnel	1	home	0
plastic pluming pipe	2	home depot	20
snow	2 pounds	mountain	0
scale	1	school	0

Detailed Procedure

1. I am going to go to go to a ski mountain and a normal mountain
2.Then I am going to take a sample from each mountain by pushing a pluming pipe down and pulling snow out with it
3. I will then need to extract snow from the piping without touching it with my hands so i don't contaminate it
4. Then I will take the snow, melt it down, and run it through a funnel with a paper filter
5. I do this with both the snow samples with two different filters
6.Then I do that nine more times

Data Analysis

All Raw Data

I originally planned non doing ph(acididy) but the levels of ph were extrodinarilly low and I was
forced to look for a differant element and setled on alkalinity.

Alkalinity level
natural
1.high,250
2.high,250
3.high,250
4.high,250
5.low,100
man-made
1.very high,1000
2.very high,1000
3.very high,1000
4.very high,1000
5.very high,1000

ph levels
man-made
1. 6.87
2.6.59
3.6.69
4.6.66
5.6.50
natural
1.6.76
2.6.95
3.6.69
4.6.82
5.6.63

Results

my results are that my hypothesis was wrong about man-made snow carrying
less toxins. It maxed out in the alkalinity tests and the natural was really low.On the
other hand the natural snow was higher in pH then the man made was.

Conclusion

I conclude that man-made snow carry more toxins then nature's snow. it will

not hurt you if you eat snow but it does carry more unhealthier toxins then natures

snow.I reject my hypothesis e and i hypothesis that when the snow from the ski

mountain and the natural snow mix, they actually filter each other out and and are cleaner.

Discussion

In my science my project i did not-is a slight pattern of the data, the man-made snow always
had a higher alkalinity level then the natural snow. I got the answer I needed and was successful
